The IRS has a new rule coming that could completely change how you save for retirement. It starts in 2027.
If you are over 50 and making a high salary, your current strategy might not work anymore. You will likely be forced into a different type of account.
This isn’t a gentle suggestion. It’s a mandate under the Secure 2.0 Act.
The Roth 401(k) requirement explained
Here is the specific detail that matters: high earners must route their catch-up contributions to a Roth 41(k).
Traditional 401(k)s let you save with pre-tax dollars. You lower your current tax bill. You pay taxes later when you withdraw the money.
Roth 401(k)s are the opposite. You pay taxes now. You withdraw the money tax-free in retirement.
Most people prefer the traditional route if they think they will be in a lower tax bracket later. High earners? They might be stuck with the Roth route.
Who does this apply to?
It only affects two groups of people. If you miss either criteria, this doesn’t touch you.
- You are 50 years of age or older.
- Your income is $145,000 (or more).
The $145,00 figure is fixed. It adjusts slightly for inflation in future years, but that is the baseline.
If you make $150,000 but you are 49? You are safe.
If you are 55 but make $130,000? You are safe.
This is a targeted rule. It is not a blanket change for all older workers.
How the 2026 catch-up limits work
Before you panic, let’s look at the numbers. You have some time. The mandate doesn’t start until 2027.
Right now, in 2025 and 2026, you have flexibility.
Standard contribution limit (under 50): $23,500.
Catch-up contribution (50-63): Extra $7,500.
Special catch-up (ages 60-63): Extra $11,250.
Total limit with employer match: $70,000. This cap excludes the catch-up amounts.
Since the rule doesn’t hit until next year, you can still use the traditional 401(k) for your catch-up funds. You can defer taxes as usual.
Max it out now while you can.
Why the shift to Roth?
Policymakers think high earners are the ones who will need the Roth benefit most.
They assume you won’t need the tax break now. You are likely already in the highest bracket. They believe you will pay the same or less in taxes later.
The logic is sound for some. It’s not for everyone.
If you have large deductions next year, the traditional route still saves you more cash in the short term.
The downside for high earners
You will pay more taxes now.
If you are pulling down a big salary, the IRS takes a bigger bite today. You lose liquidity in your current year.
You might regret this in a bad market. Or in a year you lose your job.
Those who earn less than $145,00 can stick to the traditional path. They defer taxes until retirement. This often lowers their lifetime tax burden.
It is a trade-off. You get tax-free growth with a Roth. You pay a premium now for it.
What should you do?
Check your payroll portal. See if your plan offers both Traditional and Roth options for catch-up contributions.
If you are close to the income limit? You might qualify. If you are over, you don’t have a choice.
Use the next two years to test the waters. See how the Roth account behaves in your plan.
The landscape of retirement savings is shifting. The window to choose your preferred tax treatment is closing for high-income savers.
Don’t ignore the deadline.
